Superior canal dehiscence syndrome (SCDS) is caused by an abnormal opening between the uppermost semicircular canal in the upper part of the inner ear and the brain.
The condition causes problems with hearing and balance. Superior canal dehiscence syndrome (SCDS) is an opening in the bone covering the superior semicircular canal of your inner ear. It’s a rare condition that can cause problems with your balance and hearing. Canal dehiscence syndrome (also called superior semicircular canal dehiscence syndrome, or SSCD) is a disorder that affects your balance and hearing.
superior canal dehiscence, "Dehiscence" is another word for hole... What is Superior Semi-Circular Canal Dehiscence? Vestibular and auditory symptoms and signs can result from a dehiscence (opening) in the bone overlying the superior semicircular canal of the inner ear. The Superior Semicircular Canal Dehiscence Syndrome (SSCDS) is a rare disease, mainly characterized by vestibular symptoms induced by intense sound stimuli or by changes in intracranial or middle ear pressure, due to a dehiscence of the bony layer that covers the superior semicircular canal. Around 1-2% of the general population has a dehiscence (an opening) over the superior semicircular canal, but only a portion of those people are symptomatic (have the syndrome).
superior canal dehiscence, In superior canal dehiscence, the deficit of bone overlying the semicircular canal results in a third mobile window effect, leading to areas of increased compliance and allowing for the movement of endolymph within the canal in the presence of sound and/or pressure stimuli. Superior Canal Dehiscence Syndrome (SCDS) occurs when from a small hole in the bone covering the superior semicircular canal in the inner ear. This leads to dizziness, sound-induced vertigo, and an increased sensitivity to internal noises such as heartbeat or eye movements (autophony). Superior dehiscence canal syndrome is a rare inner ear condition that affects your balance and hearing. Learn about symptoms, causes, treatment, and more.
